I have a 2014 canam ds 450efi and I recently replaced all the topped gaskets and now the Bike does not want to start. I believe I have the timing wrong but I don't know what to do at this point, I didn't lock the Crank with the bolt while rebuilding the topknot therefore the crank was Freely Spinning. The bike starts with some carb cleaner but will not start otherwise. how can I fix the timing issue. How do I find the compression stroke after the crank was freely spinning. On the magneto...

PLEASE HELP
